Considerations when using adapters
You should be aware of related information to adapters.
The following adapters or areas related to adapters have information worth noting:
Changes to EIS systems
When the EIS system you access through the discovery wizard and an adapter changes, it will have an effect on the application you created in IBM Integration Designer. Typically, this EIS change will alter a business object in some way.
For example, if you add a column on a table in an EIS system and then rediscover the EIS system or edit a service, you will find a new element in the business object (for the column). This in turn could appear as an unmapped field in a map. Since most EIS systems will change, you should expect these differences when using the tools at different points in time.
IMS
Since you work with a host based system with IMS™, you should change the default settings for the COBOL importer. They can be changed when using the external service wizard or on the operating system.
For example, in Windows from the menu, select Window > Preferences. The Preferences window opens. Expand Workbench and select Capabilities. Expand Advanced J2EE and select Enterprise Java in the Capabilities pane. Click OK. Again, select Window > Preferences. The Preferences window opens. Expand Importer. Select COBOL. In the Platform field, select z/OS. Click OK.
JDBC
The JAR for the JDBC driver of the database system that is being used needs to be added to the classpath. When using the external service wizard, you will be prompted for this JAR.
Third party libraries
If your resource adapter has third party libraries, follow these guidelines:
- Third party library: You will need to add the library to the classpath of the connector project by importing the library into the connector project. You will then need to update the classpath of the project to include the library and export it.
- Third party native library: You will need to check exactly where the native library should be placed. It is sometimes placed on the PATH variable of your machine. It might also be in the bin folder of the workbench. In the case of SAP, the third party library will be added to the lib folder of the application server.
When using the external service wizard for the IBM shipped adapters, you will be prompted for these libraries if they are required.
